So far I haven't heard anyone blame the Rock 'n Roll music
No, but it has been blamed on rap music (among other things)
however the same lack of atmosphere which gives them a boost versus ground based plants, also causes them to degrade from radiation faster.
Degradation is mainly caused by minuscule asteroids in space hitting the plastic that is shielding the solar arrays. As they are practically in a vacuum (at least if we discard the gas in space, and the numerous dense spots), they can be anywhere between barely moving to traveling at the speed of light - ie scratch it or penetrate through the array altogether. If you examine any solar cells brought back from space, you will find it like this.
Where there's a will, there's a relative.
